fing can find MAC addresses on a different network if you run it on
a system that connects to multiple nets.  I have it installed on one
of my SL5.x systems that has connections to our main net as well as
all 5 of our firewalled subnets (192.168.x.x)  By default, it just
checks the net on what it thinks is your primary nic, but you can
tell it to check any other net you have configured on that box.

Use (for example) 'fing -n 192.168.1.0/24'

Incredibly useful tool!
